Claudette Cooling, 24, started her business The Cool Line in November, launching her first collection of style statement silk scarves.

A single retweet from Theo, as part of his Small Business Sunday initiative on Twitter, led to an invite to the annual SBS event at the ICC in Birmingham where she met the Dragon’s Den star and other top UK entrepreneurs.

Every week, Theo invites small business owners across the UK to tweet him about their companies during a specific Sunday afternoon time-slot.

He chooses the best, and re-tweets them to his half-a-million followers.

Claudette was “amazed” to be chosen as one of the week’s winners.

The first she knew about the win was when her phone “went wild.”

She said: “I thought ‘why have I got 70 emails?’ - it was all retweets. I couldn’t believe it.

My followers have doubled since I won, exposure like that is great. It’s definitely worth entering as it’s such a good community.

“It can be lonely when you work on your own, so it’s nice to know that somebody believes in your business as much as you do.

“My boyfriend Connor recommended that I tweet Theo - so I’ve got him to thank, really,” she added.

The event also featured inspirational speeches and workshops with successful entrepreneurs including Holly Tucker, founder of Not On the High Street and Mike Pickles, of the Really Useful Box Company.

Theo said: “I admire people who have passion and energy. If you cannot bore your friends to death about your own small business then something is seriously wrong.

“I was struck by the number of business owners on Twitter who wanted to tell me about their new products and services. Small Business Sunday was born so that people have a specific time slot to tweet and can pitch their ‘sell’ directly to me.”

Mike and other celebrities, such as “You Don’t Own Me” singer Grace, have also engaged with The Cool Line via Twitter.

Claudette’s collection is available to buy through company’s website and from online independent marketplace, Bollo Lane.
